About Me

I build AI-powered products from zero to production - training custom diffusion models, designing ComfyUI inference pipelines, and shipping full-stack platforms that real people use.

My work spans the entire stack: LoRA/LyCORIS fine-tuning for style transfer and identity consistency, ComfyUI production workflows with 2-5x inference speedups, and full-stack web platforms built with Next.js, NestJS, and PostgreSQL.

On Civitai, I've published 121 models under the handle Sa_May, accumulating over 111K downloads, 13K+ likes, and 1,300+ followers - covering fashion, product visuals, portraits, and style systems.
